That's a header that's part of the Perl core, which (unfortunately) means that it's necessary to the workings of Inline. So there isn't going to be a way to suppress its inclusion. I think to make this work you'll need to make some sort of trivially thin wrapper functions that have function declarations in a header file that includes neither conflicting definition of U8. That way you can wrap those wrappers with Inline::C (which includes Perl's definition of U8), but declare them in a file that include the other headers that define U8. You'll need to get Inline to link to the object file created from the wrapper function file, which I'm not sure how to do, but can be done. Nicholas Clark
